Serial Data Input and Output Methods
Data is input and output using the CCB (computer control bus) format, which is Sanyo's audio LSI serial bus format.
1. Serial data input (IN1/IN2)
2. Serial data output (OUT)
Note: 1. Since the DO pin is an n-channel open drain output, the data value transition time will differ depending on
the value of the pull-up resistor and the printed circuit board capacitance values.
Note:
2. The DO pin is normally open.
